Atmospherics, eliminating; aerials. - Certain types of atmospheric disturbances or strays are prevented from affecting wireless receivers by a method based on the assumption that such disturbances possess both electric and magnetic field components, which are 90‹ out of phase, instead of being in phase as in the case of an electromagnetic signalling wave. Two aerials 1, 2 are employed, the aerial 1 being responsive to electric fields, but not to magnetic fields, and the aerial 2 to magnetic, but not to electric fields. The aerial 1 has a horizontal portion, and the down lead is shielded by an earthed screen 41 and a screening building 4, as in Specification 220,629. The other aerial 2 is vertical, and its exposed portion is surrounded by wire squares or loops 3 placed a. few feet apart, connected together aperiodically, and earthed. Electric fields are thus prevented from reaching the aerial 2, but leave it responsive to magnetic fields. The aerials 1, 2 are coupled by coils 6, 6<1> to a combining circuit 7, 8 from which connections are made to the detector 9 and telephones 10. The signalling wave produces currents 90‹ out of phase in the two aerials, and has a resultant effect in the circuit 7. 8. Strays, however, produce currents 180‹ out of phase in the two aerials, which currents neutralize each other in the circuit 7, 8.
